Miniature rose plant named ‘Poulpah026’

ABSTRACT

A new rose plant that has abundant, pink orange blended flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commerical glasshouses. This new and distintct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrid.

Variety denomination: ‘Poulpah026’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of rose plant which originated from a controlled crossing between the female parent, an unnamed seedling, and the male pollen parent, an unpatented rose named ‘Kormutric’. The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘Poulpah026’.

The new rose may be distinguished from its seed parent, by the following combination of characteristics:

-   -   1. Flower buds of the seed parent are shorter in length than         those of ‘Poulpah026’.     -   2. The seed parent has 35 to 45 petals, while ‘Poulpah026’ has         50 to 55 petals.

The new variety may be distinguished from its pollen parent in that ‘Kormutric’ has a general tonality of flower color which is yellow to yellow orange, while ‘Poulpah026’ is Red Group 35D with intonations of Orange Group 29B.

The objective of the hybridization of this rose variety for commercial culture was to create a new and distinct variety with unique qualitites, such as:

-   -   1. Uniforms and abundant Pink and orange blend flowers;     -   2. Vigorous and compact growth;     -   3. Year-round flowering under glasshouse conditions;     -   4. Suitability for production from softwood cuttings in pots;     -   5. Durable flowers and foliage which make a variety suitable for         distruibution in the floral industry.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpah026’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted elevaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poulpah026’ was selected by the inventor as a single plant from the progeny of the hybridization in June 2001.

Asexual reproduction of ‘Poulpah026’ by cuttings and traditional budding was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in April 2002. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpah026’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpah026’, as observed in its growth in glasshouses in Odense, Denmark. Observed plants were cultivated for a period of 16 weeks in 15 cm pots. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

For a comparison, several physical characteristics of ‘Poulnil’, a rose variety from the same inventor described and illustrated in U.S. Plant Pat. No. 13,301 issued Dec. 3, 2002, are compared to ‘Poulpah026’ in Chart 1.
